R. corda Drc. (= grisea Schs.) (153 b) has silvery grey forewings, the costal margin shaded brown, corda. 
with a small black basal spot and dark brown double transverse lines, the posterior one transformed into a 
broad brown band before which there are single deep black spots. Hindwing whitish with a broad dark grey 
marginal band. Expanse of wings: 40, $ 43 mm. Colombia. 
R. phasma Dogn. Eorewing greenish ochreous (the fresh specimen probably of a purer green), the phasma. 
basal half of the inner margin black with fine black transverse lines composed of deep lunae; the distal half 
of the cell and the postdiscal area behind it darkened by extensive black shading, a black subterminal shadow 
reaches neither the costal margin nor the inner margin. Hindwing yellowish-white, blackened at the costal 
and inner margins, grey at the distal margin. Expanse of wings: 38 mm. Brazil and Argentina. 
R. spontiva Dogn. (153 b) is a beautiful species coloured green and red-brown, the greenish-white spontiva. 
ground traversed by numerous partly olive black partly red-brown dentate transverse lines, a very broad dark 
olive green oblique band between them extends from the first quarter of the costal margin to the anal angle 
before which it disappears; a still darker triangular spot behind the cell at the costal margin almost to the apex; 
the 3 distal postmedian lines are broken up into dots, the ground between them partly filled with red-brown. 
Hindwing blackish, the anal spot parted by white. French Guiana, Colombia. 
R. elgiva Schs. (153 b) is a large species, greyish-brown mixed with black, the distal half of the forewing elgiva. 
of a somewhat purer brown, with dark veins and fine blackish-brown double transverse lines and basal ray; 
the dark ring-macula and reniform macula are surrounded by white; the undulate line is a dark dentate shadow. 
Hindwing reddish-brown, the black anal spot parted by white. Expanse of wings: 55 mm. French Guiana. 
R. imitata Drc. is a strange insect exactly like the well-known Proelymiotis aequipars ( 1 44 g); fore wing imiiaia. 
light greenish-grey, broadly dark brown in the basal half, distally bordered with black, with a small dark brown 
spot near the apex, one above the anal angle and a somewhat larger quadrangular one between veins 3 and 4: 
black submarginal streaks. Hindwing greyish-brown, darkened at the margin, with a black anal spot. Trinidad. 
R. mistura Schs. (= cossoides Rothsch.) (153c) is one of the largest species; forewing greenish-grey, mistura. 
mixed a little with brown, deep chocolate-brown in the basal third in the costal-marginal half, and with a 
similarly coloured apical spot, with more or less distinct double brownish transverse lines and a fine black sub- 
terminal line; whitish brightening postdiscally below the apical spot. Hindwing dark brown, fringe lighter. 
Expanse of wings: 67 mm. Guiana, Brazil (Amazons). 
R. albidivisa Dogn. is very closely allied to mistura, separated by a more curved double anterior trans- albidivisn. 
verse line, with more white dusting behind it, a merely rounded reniform macula which is entirely reniform 
in mistura, 2 white-strewn spots before the posterior transverse line at the inner margin. This species described 
from French Guiana is also somewhat smaller. Expanse of wings: 64 mm. 
R. lemoulti Schs. (153 c) is somewhat similar to the preceding species, but the dark basal part is replaced lemoulti. 
here by a light, reddish-yellow area distally bordered bv red-brown lines and longitudinally traversed by 
fine red-brown lines; apex light reddish-brown with deep black longitudinal streaks. Hindwing dark brownish- 
grey with light- reddish-yellow fringe. Expanse of wings: <$ 63, $ 76 mm. Guiana, Brazil. 
R. culpata Schs. is still larger than lemoulti and very similar; distinguished by lighter reddish-brown culpata. 
hindwings with a dark median line distally bordered with reddish-yellow, and a broad darker brown subterminal 
shadow; fore wing darker grey, the basal third darker, more brownish, the reniform macula at the cell-end is 
larger, the red-brown apical spot with a darker border without black streaks in it. Expanse of wings: 69. 
$ 83 mm. Costa Rica. 
R. biplaga Rothsch. (153 d) is a very large easily recognisable species from the lemoulti- grouj), similarly biplaga. 
marked, but the forewing is mixed with lighter and darker brown and exhibits 2 very characteristic greyish- 
white spots at the inner margin, separated by the median shadow; a reddish-brown spot at the base of the inner 
margin, and a long black streak at the apex. Hindwing dingy brown with a darker, distally lighter median 
shadow. Peru, Bolivia. 
R. everiti Schs. is also a very large species. Forewing whitish, strewn with reddish-brown and everiti. 
ochre, a black irregular spot at the base of the costal margin; transverse lines black, the anterior one double, 
connected with the basal spot by a black spot below the cell, the cell above it whitish; the oval white reniform 
macula is narrow, bordered with blackish-brown; a reddish-brown subterminal shadow below 4 extends to the 
margin and anal angle; a thick black oblique streak extends from the post-median line towards the apex. Hind¬ 
wing brownish-black with an indistinct postmedian line and a black and white anal spot. Expanse of wings: 
65, $ 80 mm. French Guiana.
